Bang & Olufsen Calibration Microphone

This Bang & Olufsen calibration microphone is perfect for calibrating BeoLab 50 / BL50, BeoLab 90 / BL90 and Beosound Theatre sound systems. The microphone was purchased with a Beosound Theatre in 2024 and is in excellent condition. The adapter for BeoLab 50 / 90 was purchased in September 2024. The original microphone for BL50/90 is now discontinued, so B&O now uses this one instead with the original adapter. Comes with original packaging.
